It can be used to create groups of processes whose members send messages to each other. JGroups enables developers to create reliable multipoint (multicast) applications where reliability is a deployment issue. JGroups also relieves the application developer from implementing this logic themselves.
1331:
The most powerful feature of JGroups is its flexible protocol stack, which allows developers to adapt it to exactly match their application requirements and network characteristics. The benefit of this is that you only pay for what you use. By mixing and matching protocols, various differing

Instances of the chat application can be run in the same process, on the same box, on different hosts in the local network, on hosts in different networks, or in the cloud. The code remains the same; only the configuration needs to be changed.
1322:
For example, in a local network, IP multicasting might be used. When IP multicasting is disabled, TCP can be used as transport. When run in the cloud, TCP plus a cloud discovery protocol would be used and so on...
1311:
Then, the channel joins cluster "ChatCluster". From now, messages can be sent and received, plus a new view (including this member) will be installed in all cluster members (including the newly joined member).

This saves significant development time and allows for the application to be deployed in different environments without having to change code.

application requirements can be satisfied. JGroups comes with a number of protocols (but anyone can write their own), for example
1315:
Anything typed in the main loop results in the creation of a message to be sent to all cluster members, including the sender.
